Embodiments of a system and method for migrating data from a first cloud network provided from a first cloud service provider (CSP) and a second cloud network provided by a second CSP. The method reads and packs only live data containers from the first cloud using a Garbage Collection (GC) process. It performs a collection replication process replicating a local container set (CSET) from the first cloud network to the second cloud network, and replicates data containers from the first cloud network to the second cloud network. It then uses a container manager process to write data containers on the second cloud network.

Migrating deduplication file systems having cloud units from different cloud providers

Embodiments for balancing cloud resource capacity for cross-node movement of files in a scaled out backup system, and for dynamically allocating cloud storage resources in a multi-node network having a file system. A process determines a destination node with dedicated cloud storage capable of storing a file selected for long term retention. It transfers the file to the cloud storage of the destination node while maintaining metadata of the file in the cloud tier local storage of the destination node, such as by using remote procedure calls between the destination and source nodes. It then updates a global namespace of the file system with a handle indicating a current location of the file as the cloud storage of the destination file, thus allowing access to the file through the metadata stored in the local storage of the source node.
